Obviously, there is something going on here and this might be a way to keep some quiet in the game.

NY TIMES-

Jeffrey H. Knox, a senior federal prosecutor who butted heads with a number of Wall Street banks, is switching sides.

The Justice Department announced on Tuesday that Mr. Knox, chief of its fraud section, was leaving the government. In turn, the law firm Simpson Thacher Bartlett released its own announcement: Mr. Knox will join the firm as a partner in Washington.

The move by Mr. Knox, which caps more than a decade-long prosecutorial career, comes just as one of his biggest Wall Street cases nears a turning point. The Justice Department, along with regulators in Washington and London, is closing in on actions against some of the world’s biggest banks for suspected manipulation of foreign currencies.
